Improvement in arrangement of conducting pipes and manifolds



UNITED STATES PATENT OFFICE.

CALEB G. WALWORTH, OF BOSTON, MASSACHUSETTS.

Specification forming part ot Letters Patent No. 38,433, dated May 5, 1863.

To all whom it may concern:

Be it known that I, CALEB C. WALwoRTH, of Boston, in the county of Suffolk, in the State of Massachusetts, have invented a new and Improved Combination of Conducting Pipe, Valve, and Manifold; and I do hereby declare that t-he following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

This invention consists in an improved manner of combining the branch T77 or manifold 7 with a valve and conducting pipe, whereby the many parts and joints and much ofthe labor, material, and room heretofore involved in the ordlnary manner of combining conducting-pipes, valves, and manifolds are saved.

The usual form of the branch T or manifold is that of a tube having several branches or outlets on one side thereof, to or in which outlets the radiating-pipes are iixed, and the conducting-pipe has been connected with this manifold at one end thereof by pipes and other fittings]7 including a valve which is located entirely outside of and between the manifold and the conducting-pipe, and in the line or course of the connecting-fittings. This manner heretofore employed of combinin g the conducting-pi pe, the valve, and manifold involves the use of an unnecessary amount of material, the employment of a number of separate parts which have to be joined, and which are l-iable to leak at the `joinings, and these joints are expensive to make and to put together, and are not neat in their appearance. lt may here be stated thatin this speciIica-tion Il mean by conducting-pipe,77 those vertical pipes whichlconduct the steam to the manifolds, or the water of condensation from them in contradistinction to the horizontal radiating-pipes from the manifolds, and to suoli pipes as conjointly with fittings have heretofore been used to connect the ordinary form of manifolds with the vertical conducting-pipe.

In the drawings, Figures 1, 2, and 3 are vertical cross sections illustrating various embodiments of my invention, Fig. l showing three branches, c, for the reception of radiating-pipes, and the valve e, located centrally with respect to the length of the manifold. Fig. 2 shows a manifold with six branches, the upper ones being separated from the lower ones by a partition, f, in the manifold, thus, in fact, dividing it into two separate and independent manifolds, each of which has its own independent valve, both ot' which valves regulate communication with one conducting-pipe common to both parts of the divided mani. fold. Fig. 3 shows two manifolds, each with three branches, and located on opposite sides of the conductingspipe, each of which manifolds has its own independent valve for regulating communication with the conductingpipc. Fig. 4 is a horizontal cross-section taken in the lines z z. (Seen in Figs. l and 2.)

a represents a portion of the conducting pipe, which is constructed with the manifold. It is provided at each end with screw-threads, whereby it is coupled in the line of conduct ing-pipe, or whereby it may be coupled to the upper end of the conducting-pipe, the upper end of the section, marked a, being stopped with a screw-plug. The branch T or manifold is represented by b, and as cast integral with (t, and so that the sides of a, marked cl, form the partition between and common to the manifold and conducting pipe, in which partition the valve-seat may either be formed or fixed. The valve c controls the only passage between the manifold and the conduct. in gpipe.

There being nothing new or peculiar in the construction of the valve and its appendages, and these being clearly illustratedin the drawings, nothing further in their description is needed. When the valve is located beyond the outlets c, as shown in Fig. 3, and Whether the outlets are from more than one side of a or not, it will be seen that av position of the combination reversed from that shown in said tigure will permit all of the water which enters the radiating-pipes, or which forms therein by condensation, to drain oft' into the conductingpipe, the valve in this casebeing located in the lowest part of the manifold, where the water naturally settles.

It is not novel to form branches or outlets in conducting-pipes, these branches being on the sides of such pipes, and forming openings directly into them, and each outlet or branch having a valve-seat formed or fixed therein so that passage through each outlet is controlled by its own valve. This arrangement is expensive from its requiring so many valves, there being one to each outlet or branch, and

it differs from mine in that it; lacks the parti- In Witness whereof I have hereunto Set my fcion d, whereby one valve controls the passa-ge hand this Zith day of March, A.
